Lisa says in the beginning of the episode that the Nobel Prizes are in Stockholm. For the rest of the episode, they are in Oslo.
In announcing Krusty's supposed win of the Nobel Peace Prize, Kent Brockman incorrectly includes Mohandas Gandhi in the list of past Nobel Peace laureates.
During the episode a clip is shown that Krusty was in south Africa in 1990. He then gets angry and asks the orchestra to 'vuvuzela me out of here'. The orchestra then blows on vuvuzelas. The vuvuzela's depicted were only manufactured and named 'vuvuzela's' in the year 2002.
